We have met Dr Johnston when son was hospitalized for AV canal defect heart failure. He speaks very softly and answers all the questions. He make you feel comfortable to ask questions. Wonderful doctor!

Dr. Johnston has been my daughter's heart doc for years. She is in college now and still sees him. He has a wonderful bedside manner, treats her with respect, and thoroughly explains her options. What a blessing to have found him!

We first met Dr. Johnston when our newborn baby, Avery was less than 2 weeks old. Dr. Johnson has delivered some hard news in a professional and consise manner but has also laughed with us and enjoyed watching Avery thrive and grow. It is never easy to have a child who requires this level of medical care, but I am thankful everyday to have someone like Dr. Johnston on Avery's team. He is a wonderful doctor and a great person. I would recommend him to any other worried mommy.

Dr. Johnston has been there for every cath my son has had (and unfortunately he has had more than his fair share.) He has worked closely with our son's cardiologist and together they have decided the course of care. Dr. Johnston is honest in his explanations, and he does an excellent job making the entire process easy to understand.
